//Viewed in light of Western diatonic theory, the three extra steps (of 34-et compared to 31-et) in effect widen the intervals between C and D, F and G, and A and B [that is: 6 5 3 6 5 6 3], thus making a distinction between major tones, ratio 9/8 and minor tones, ratio 10/9.// ([[http://en.wikipedia.org/wiki/34_equal_temperament|Wikipedia]]) | //Viewed in light of Western diatonic theory, the three extra steps (of 34-et compared to 31-et) in effect widen the intervals between C and D, F and G, and A and B [that is: 6 5 3 6 5 6 3], thus making a distinction between major tones, ratio 9/8 and minor tones, ratio 10/9.// ([[http://en.wikipedia.org/wiki/34_equal_temperament|Wikipedia]]) | ||
*The sharpness of ~13 cents of 11/8 can fit somewhat with the 9/8 and 13/8 which both are about 7 cents sharp. Likewise the 20-cent sharpness or flatness of either approximation to 7/4 isn't impossible. The ability to tolerate these errors may depend on subtle natural changes in mood. [[68edo]], double 34, has both these intervals in more perfect form | *The sharpness of ~13 cents of 11/8 can fit somewhat with the 9/8 and 13/8 which both are about 7 cents sharp.

The chain of fifths gives you the seven naturals, and their sharps and flats. The sharp or flat of a note is (what is commonly called) a neutral second away - the double-sharp adds up to a minor third away. This has led certain complainers, aiming to notate 17 edo (which is relatively popular), to want an extra character to raise something a small step of which. The 34 tone equal temperament, however, can be constructed from two equally spaced 17-note scales: a symbol indicating an adjustment of 1/34 up or down also serves the purpose of the previous sentence, by using two of it. This systemology of course emphasizes certain aspects of 34-edo which may not be most efficient expressions of some musical purposes: The reader can easily construct his own notation. One concern is that a system with 15 nominals for example, instead of seven, might be waste - of paper, space, brainmemory etc. if they aren't used consecutively and frequently. The system spelled out here has familiarity as an advantage or disadvantage. Tangentially, while the table uses ^ and v for "up" and "down", Kosmorosky prefers using filled in triangles because that's what I decided on years ago, and | The chain of fifths gives you the seven naturals, and their sharps and flats.
